AUTOMOBILE LOCK.

Application-'filed ApriIB, 1925. Serial No. 20,513.

the gas line, the line of communication between the carburetor and the working cyl-` inders `of the motor, our object being the provision of a simple, inexpensive arrangement which maybe readily and quickly api plied, which will be lastingl and durable and which will be uniformly effective and eilicient in use.- i

In the accompanying drawing, `which illustrates our present invention andforms a part of this specification:

Figure 1 is a vertical longitudinal section' illustrating the practical application of our invention, Y Y

Figure 2 is a detail cross section taken on line 2-2 of Figure 1, with the parts in position they assume when the lock is in effective position, and

Figure 3 is a detail perspective view of the spring take-up washer utilized in connection with the valve plug.

Referring now to these figures and particularly to Figure 1, there is shown at 10 a carburetor of an automobile or other motor car, which usually supplies to the engine or motor a combustible mixture through an in-take manifold 11, the latter or other part of the supply connections forlthe combustible mixture being provided in accordance with our invention with an angular bore for the reception of the valve plug 12 having a transverse opening 13 which when the valve plug is turned in one position forms a part of the gas supply channel 14. This plug when turned at right angles to its normal position shown in 'Figure 1 serves to cut off passage of combustible mixture through the gas channel 14 and is adjustably supported at its lower free end by means of a set screw 15 threaded through one wall of the manifold 11 at the base of its above mentioned bore.

At the opposite end of its bore, the manifold 11 is threaded for the reception of a cap labove the turningplug l2, and be-` tween this cap 16 and the adjacent or `upper end ofthe turning plug 12, a spring washer 17 is disposed, the function of which is to press the valve longitudinally and yieldingly maintaining the same in engagement with the adjusted screw 15 at all times.

The screw cap`16 has acentral bore for the lower end of the valve stem 18, the latter of which is rigidly connected to the upper end ofthe valve plug 12, and the cap 16 also has at the upper end of its stem receiving bore a counter bore and is internally threaded around the latter to receive the lower threaded end of'a tube 19 which forms a housing for the valve stem 18. f

yThe valve stem 18 and tube `19 forming the housing thereof upstand tothe dash or instrument board of the vehicle, the latter of which has an opening to receive one end of the tubular body 21of a lock'head having a flange 22 Secured against the face of the dash or instrument "board by a series of bolts or rivets 2 3. This body 21 forms alock casing-and has a bore in whicha lock barrel 24 is rotatable under control of tumblers 25 or in other words is rotatable when the key 26 is inserted in the barrel in order to set the tumblers in proper position. The barrel 24 has at its upper outer portion an angular arm or handle 27 and is provided at its inner portion with a surface groove angularly thereof for the reception of the inner portion of a set screw 28 threaded angularly through a portion of the casing 21 and which it will be particularly noted is covered when the casing is secured to the dash or instrument board so as to defeat any attempt to pull the barrel outwardly while the casing is secured to the dash.

The inner reduced portion of the barrel 24 is axially bored to receive the upper end of the valve stem 18 and the upper end of the valve stem is secured within this bore by a set Screw at 29 threaded into engagement with the stem through a threaded bore in the inner reduced end of the barrel 24, which set screw is insertable and removable through an opening 30 of the lock casing when the barrel 24 and consequently the turning plug valve 12 are in one position, namely, the normal operating position. When the key 26 is inserted and the barrel rotated through 180 degrees so as to move the turning plug valve to the locked position, the set screw 29 is shifted out of aline- Q V r L y 1,555,052

ment with the opening 30 and cannot be removed by unwarranted persons while the device is in locked position. Y

The casing 2l is internallytthreadedat the lower forward `end y'ofits bore to receive ing the valve stern housing and there is also preferably associated therewith a lock nut 3l abutting the lower forward end of the casing so as to 4insure rigidlunion fof'theseparts. s
